Abandon the "old" infrastructure for --input-file (mp_input_add_fd(), select() loop, non-blocking reads). Replace it with something that starts a reader thread, using blocking input. This is for the sake of Windows. Windows is a truly insane operating system, and there's not even a way to read a pipe in a non-blocking way, or to wait for new input in an interruptible way (like with poll()). And unfortunately, some want to use pipe to send input to mpv. There are probably (slightly) better IPC mechanisms available on Windows, but for the sake of platform uniformity, make this work again for now. On Vista+, CancelIoEx() could probably be used. But there's no way on XP. Also, that function doesn't work on wine, making development harder. We could forcibly terminate the thread, which might work, but is unsafe. So what we do is starting a thread, and if we don't want the pipe input anymore, we just abandon the thread. The thread might remain blocked forever, but if we exit the process, the kernel will forcibly kill it. On Unix, just use poll() to handle this. Unfortunately the code is pretty crappy, but it's ok, because it's late and I wanted to stop working on this an hour ago. Tested on wine; might not work on a real Windows. |

mpv
Overview
mpv is a movie player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types.
If you are wondering what's different from mplayer2 and MPlayer you can read more about the changes.
Compilation
Compiling with full features requires development files for several external libraries. Below is a list of some important requirements.
The mpv build system uses waf but we don't store it in your source tree. The script './bootstrap.py' will download the latest version of waf that was tested with the build system.
For a list of the available build options use ./waf configure --help. If
you think you have support for some feature installed but configure fails to
detect it, the file build/config.log may contain information about the
reasons for the failure.
NOTE: To avoid cluttering the output with unreadable spam, --help only shows
one of the two switches for each option. If the option is autodetected by
default, the --disable-*** switch is printed; if the option is disabled by
default, the --enable-*** switch is printed. Either way, you can use
--enable-*** or --disable-** regardless of what is printed by --help.
To build the software you can use ./waf build: the result of the compilation
will be located in build/mpv. You can use ./waf install to install mpv
to the prefix after it is compiled.
NOTE: Using the old build system (with ./old-configure) should still work,
but will be removed in a future version of mpv.
Essential dependencies (incomplete list):
- gcc or clang
- X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...)
- Audio output development headers (libasound, pulseaudio)
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libavresample) At least FFmpeg 2.1.4 or Libav 10 is required.
- libjpeg (for screenshots)
- libquvi if you want to play Youtube videos directly
Libass dependencies:
- gcc or clang, yasm on x86 and x86_64
- fribidi, freetype, fontconfig development headers (for libass)
FFmpeg dependencies:
- gcc or clang, yasm on x86 and x86_64
- OpenSSL (has to be explicitly enabled when compiling ffmpeg)
- libx264/libmp3lame/libfdk-aac if you want to use encoding (has to be explicitly enabled when compiling ffmpeg)
- Libav also works, but some features will not work. (See section below.)
Most of the above libraries are available in suitable versions on normal Linux distributions. However FFmpeg is an exception (distro versions may be too old to work at all or work well). For that reason you may want to use the separately available build wrapper (mpv-build) that first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.
If you are running Mac OSX and using homebrew we provide homebrew-mpv, an up to date formula that compiles mpv with sensible dependencies and defaults for OSX.
FFmpeg vs. Libav
Generally, mpv should work with the latest release as well as the git version of both FFmpeg and Libav. But FFmpeg is preferred, and some mpv features work with FFmpeg only. See the wiki article about the issue.
Release cycle
Every few months, a new release is cut off of the master branch and is assigned a 0.X.0 version number.
As part of the maintenance process, minor releases are made, which are assigned 0.X.Y version numbers. Minor releases contain bug fixes only. They never merge the master branch, and no features are added to it. Only the latest release is maintained.
The goal of releases is to provide stability and an unchanged base for the sake of Linux distributions. If you want the newest features, just use the master branch, which is stable most of the time, except sometimes, when it's not.
Releases other than the latest release are unsupported and unmaintained.
See the release policy document for more information.
Bug reports
Please use the issue tracker provided by GitHub to send us bug reports or feature requests.
Contributing
For small changes you can just send us pull requests through GitHub. For bigger changes come and talk to us on IRC before you start working on them. It will make code review easier for both parties later on.
Contact
These forms of contact are meant to ask questions about mpv usage, give feedback on mpv and discuss it's development.
If possible, please avoid posting bugs here and use the issue tracker instead.
